The parental DNA test is done to bring about the fact of the legal and the biological relationship between the parents and the child. Though this test is done for a formal reason in certain places, there are certain situations where the test may be made compulsory by the government. This type of parental DNA test is done when the child is born in another country and does not carry any evidence, that the child is the son of the citizen of the country. During such cases this parental test is conducted. Though this type of test will be troubling the parents and leave the parents in an embracing situation in certain cases, this test is mandatory.
